Thanks!
Sounds like you might have hydroids. They are pretty common. I would think that Banggais are really too big to be prey for them, but the hydroids will eat all the BBS and reproduce like crazy.
There's a picture here of the medusa stage: http://www.aquariumboard.com/forums/general-marine/2567.htm
If they start to be trouble you can scoop out the Banggai fry and switch them to a new tank, trying not to get any of the hydroids in the scooped water. Then when you're done bleach the old larvae tank. If you want to be really conscientious, neutralize the bleach with one of the aquarium bleach removers they sell for freshwater before you dump the cleaning water so that the bleach doesn't get into the water supply.
